WIND OW-FASTENER.

Application led March 31, 1916.

To all fr0/tom t may concern Be it known that I, Janus A. BURKE, a citizen of the United States, residing at Ligonier, in the county of lestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in 7indow-Fasteners, of which the following is a specification.

This invention relates to an improved window fastener and the principal object of the invention is to provide a fastenerl so constructed that a` window may be releasably held at a desired position in the frame and to further construct the fastener that it will be normally held in a position for engagement with a rack connected with the window frame, the engaging plunger being vieldably held in the operative position and provided with means for permitting` of its being' easily moved to an inoperative position.

Another object of the invention is to so construct this fastener that the racks forming part of the same may take the place of the usual guiding strip for the window frame.

Another object of the invention is to provide a fastener which will be very simple in construction and which can therefore be produced at a very small cost.

T his improved window locl is illustrated in the accompanying drawings, wherein Figure 1 is a view in front elevation showing the device applied to a window.

Fig. 2 is a sectional view taken along the line 2-2 of Fig. 1.

Fig. 3 is a view in elevation of the fastener with the front plate removed.

This 'improved fastener is used for releasably holding the upper and lower window sashes 10 and 11 at a desired position in the window frame 12 and may be positioned either at the side shown in Fig. 1 or upon the opposite side. It is also obvious that if desired.` a fastener can be provided at each side of the window. hen in use the beading is removed from that side of the window frame 12 with which the fastener is to be connected and the racks 13 are put in place where they will serve as means for guiding the movement of the window sash in the frame. These racks are each provided with a flange or extension 14E through which the securing screws or other fasteners 15 indicated by dotted lines in Figsl and. 2 will pass These racks are Specification of Letters Patent.

provided with teeth 16 for engagement by the fasteners carried by the window sashes and it will thus be seen that when the window sashes are moved vertically in the window frame they may be releasably held at the desired position.

The fastener' is provided with a housing 17 having an inturn flange 1S forming a good support for the cover plate 19, the cover plate being held in engagement with the housing by means of screws or other fasteners 2O which pass through openings 21 formed in the flange 1S. The latch pin 22 which engages the teeth of the rack bars is slidably mounted in the housing and is yieldably held in the extended or operative position by means of the spring positioned as shown in Fig. 3 and engaging the head of the latch pin. A stem or actuating handle extends from the latch pin 22 v through the top portion of the housing 17 and may be bent as shown in Fig. 3 to permit easy handling of the same or may be provided for connection with a line or chain 2G as shown at the upper portion of Fig. 1.

v"(.lhcn this device is in use the handle 25 of the lower fastener will be moved with one finger and as soon as latch pin 22 is out of engagement with the racks 13, the lower sash can be raised and the latch pin then released and permitted to return to the operative position. In order to lower the upper sash, the line or chain is drawn to move the latch pin to the inoperative position and the upper sash can then be lowered to the desired point. The line or chain can then be released and the upper sash will be releasably held at the adjusted position. It will thus be seen that this device is very simple in construction but at the same time is very effective in use and will not easily get out of order or need repairs.

A window frame. a sash slidably mounted in said frame, a strip guiding the movement of said sash and provided with a toothed flange forming a rack bar, a housing connected with said sash and having its walls provided with inwardly extending flanges, a closure plate fitting against the flanges of said housing and connected therewith, a latch pin slidably mounted in said housing and extending through one end thereof, an abutment head at the inner end of said latch pin curved transversely, a spring positionedl between said head and one of the end walls of said housing to yieldably hold said latch pin in an extended position for engagement with said rack bar, and an actuating pin extending from said latch pin and having its outer end portion bent to provide an engaging hook.

In testimony whereof I a'HX my signature 1n presence of two witnesses.
